I m using sqlserver there is table name of Attendence
Columns of Tables are

1)EmpCode int
2)AttendenceDate datetime
3)AttendenceTime Datetime
4)status tinyint

Data in table would be like this

Code AttendenceDate AttendenceTime status
1001 3/27/2009 3/27/2009 9:05 1
1001 3/27/2009 3/27/2009 7:05 0

1002 3/28/2009 3/27/2009 10:05 1 //user didnot checkout

1003 3/29/2009 3/27/2009 7:05 1
1003 3/29/2009 3/27/2009 7:05 0

1001 3/30/2009 3/27/2009 7:05 1
1001 3/30/2009 3/27/2009 7:05 0
1003 3/29/2009 3/27/2009 7:05 0 //User didnot checkin

when we find "1" in staus it means its checkin and "0" means Check out
i have to make query to show the result like this

Code date Time in Time out
1001 3/27/2009 9:05 7:05
